Domestic first shale water -based drilling fluid "slimming well" successfully finished drilling

Hubei Daily News (correspondent Shi Jianfen, Wang Bin, Lin Anguo) On September 23, Jianghan Oilfield deployed the coke page 26-Z1HF well in Fuling shale gas field. Skin structure + high -performance shale water -based diamond -drilling shale gas well.

After the drilling depth of 5470 meters, the horizontal section was completed, and the drilling was completed, setting a number of records such as the longest, horizontal displacement, and maximum volume ratio of domestic shale gas wells in the domestic shale gas well.

The promotion and application of shale water -based drilling solution technology is an important measure during the "14th Five -Year Plan" period of Jianghan Oilfield. It is of great significance to promote the realization of "green development" and accelerate the cost reduction. The Jianghan Oilfield Engineering Technology Management Department led by the joint efforts of relevant departments and units, actively developing high -performance shale water -based drilling solution technology and conducting on -site experiments, achieving major breakthroughs.

In response to the problems of the platform's well -intensive, high -touch risk, and high fracture interference, the oil field engineering technology management department has the courage to innovate, and cooperate with Fuling Rock Gas Company, Technical Supervision Center, Engineering Academy, relevant scientific research institutions, and drilling construction units. Establish a technical research team to formulate special technical measures, risk prevention and control measures, and single -well acceleration optimization solutions.

In the next step, Jianghan Oilfield will be preferred to conduct a total of 11 wells on platforms such as coke pages 26#, coke pages 34#, and coke pages 67#to conduct tests to conduct in -depth promotion and application of high -performance shale water -based drilling solution. This is a good demonstration.

The Hubei Daily client, paying attention to the major events of Hubei and the world, not only pushing the authoritative policies for users, fresh hot information, and practical convenience information, but also launched a series of features such as reading newspapers, newspapers, learning, online interactives.
