Why Drill Pipe Prices Still Decline

Why is the price of drill pipe still falling? It was reported on the 24th that the price of 62% imported refined iron powder reached 99.4 US dollars per ton, down 10.8 US dollars per week. The industry may be approaching the bottom. On the 27th, traders were struggling with the distribution policy. 63.5 percent of Indian fine ore futures were quoted at US $106-US $108 per ton, falling sharply below the psychological threshold of US $120 per ton. Compared with the quotation of more than US $200 per ton at the beginning of the year, it is close to "halving"., Recent ore prices have fallen to their lowest levels since late 2009. 28, water well drill pipe price analysts said that the next period of time.

Discussion on the Problem of Inhibiting Rock Cuttings Slurry to Stabilize Drilling Fluid Performance

DTH drill pipe occupies a very important position in the drilling accessories. When the drilling rig is working, under the condition that the formation is relatively stable, the solid-free drilling fluid is used. As long as enough flocculant is added, the cuttings will easily settle on the ground and keep the drilling fluid stable.

Some Factors of Formation Leakage in Water Well Drill Pipe Analysis

Water well drill pipe analysis of some factors of formation leakage, first of all, what are the prerequisite factors of formation leakage?

What are the causes of borehole collapse under geological drill pipe analysis?

The water-sensitive shale formations, such as Zhiluo Formation, Fuxian Formation, Liujiagou Formation, Shi Qianfeng Formation and so on, weaken their mutual connection force and eventually collapse.

Drill pipe on the advantages and disadvantages of rock debris slurry!

Everything has two sides. The same is true for rock debris pulping. It has its advantages and disadvantages. Use its advantages and abandon its disadvantages. This is the principle. In the drilling work of drill pipe, rock cuttings slurry will also play a very important role. The following is an introduction to the disadvantages of drilling caused by rock cuttings slurry:

How to Plugging the Gravel Layer under the Loess Layer by Geological Drill Pipe

The geological drill pipe shall be drilled with clean water and then the casing shall be cemented with cement. If the water source is sufficient, use clean water to drill to the designed well depth, then lower the casing and fix the casing firmly with cement.

How to allocate drilling fluid for outer flat drill pipe?

In the normal operation of the outer level drill pipe, if the cuttings are not easy to return, it is easy to cause buried drilling accidents. Therefore, if it is found that the amount of cuttings returned outside the well is reduced or not returned, the drilling fluid performance should be adjusted immediately until the amount of cuttings returned is normal.

Method of Stickling of Water Well Drill Pipe for Adhesion Stickling

The drill pipe of water well may be unstuck by jarring method within 30 minutes after sticking. Pull up and then slam or rotate. If there is no effect after 30 minutes of activity, do not move again. If it is a straight well, press down 2/3 of the weight of the drill pipe above the stuck point to bend the drill string, reduce the contact area with the well wall, and prevent the stuck point from moving. If it is a horizontal well or an inclined well, it cannot be pressurized, because the lower drill string is all on the lower side of the well wall, and the more it is, the more dead it is.

What are the preventive measures for reducing diameter sticking in outer flat drill pipe?

When the outer flat drill pipe is in the stratum without spalling but shrinking strength, use clean water and polyacrylamide (adding 0.2) to drill to the front 10 m of the shrinking formation. Add 2.5 potassium chloride or 1.5 potassium silicate or 1% broad-spectrum wall protecting agent type I at one time according to the whole drilling fluid, and the shrinking formation will no longer shrink.

Depth analysis of friction welding drill pipe on drilling steps:

The design of pipe sleeve can be said to be the highlight of drilling. Any well in the friction welding drill pipe drilling process often encounter several different geological, depth or emergency conditions, production and development needs, so it is necessary to several layers of casing to protect the well hole, in order to smoothly drill to the drilling target.
