9000 meters!China Petroleum Create the deepest in the country

PetroChina's ultra -deep well drilling capacity to a new level. At 13:10 on June 23rd, China Petroleum was safe in the southwestern oil and gas field Pisces, and it was safely drilled to 9010 meters well.

Pisces 001-H6 well is a super well deep, ultra-high temperature, and ultra-high-pressure horizontal well in the Pisces Block field dam. Drill logs show that the well temperature exceeds 180 degrees Celsius, the strata pressure exceeds 130 MPa, and the hydrogen sulfide content is 6 grams per cubic meter.

The horizontal section of the eye trajectory control is the biggest difficulty of construction. First of all, it is necessary to accurately determine where to be buried in a few meters of a few meters outside of the ground, and the target "dessert area" must be used to ensure that the oil and gas can be found. China Petroleum Chuanqing drilling adopts independently developed international advanced "CQ-IGS horizontal integration geological orientation technology", which refined the real-time drilling trajectory of nearly 8,000 meters underground for more than 1 kilometer.

The storage layer "dessert area" is well well. Whether the drill can be advanced in the reservoir, it can truly test the technical strength of the Sichuan celebration drilling. In the construction of Pisces 001-H6 well, the drill was extended from the ground to 9 kilometers from the ground through a roots. If you want to control the drill with a diameter of 149.2 mm diameter 9 kilometers away, the difficulty is no less difficult than the closer line of a 100 -meter piercing. Chuanqing drilling relies on advanced and mature directional well technology, and the horizontal section of the well's eye trajectory is smooth and stable.

Drilling fluid is known as "drilling blood" and affects the success of drilling. Chuanqing drilling adopts an independent research and development of the anti -high -temperature -resistant oil -based oil -based drilling liquid system. In the horizontal well drilling drilling, the well wall is stable without collapse. At the same time, creative exploration uses the oil -based drilling liquid system with high temperature and strong blocks to reinforce the body lubricant glass micro beads, etc., and successfully solves the problem of ultra -deep well -oriented deserture, which provides a strong support for the smooth drilling of the well.

China Petroleum actively explores the "three highs" (high temperature, high pressure, high sulfur -containing) gas well efficient exploration and development model, strengthen scientific and technological innovation drivers, and use the 9,000 -meter deep well electric drilling rig independently developed by my country, fine control of the whole process, etc. Core technology and equipment have achieved major breakthroughs in the field of ultra -deep oil and gas exploration.
