Daqing Oil Field horizontal well controlled wear layer fracturing tests are successful

The
new station of Daqing oilfield nine plants outside the expansion block to big
415 two horizontal wells flowing. The
flowing, starting from the wear layer of the plant to carry out large-scale
horizontal well controlled fracturing test. May
10, two wells are still in the trial mining spray fishing oil production phase,
converted to an average of wells with crude oil production amounted to about 15
tons.
Since there had been sprayed in the history of the Daqing Oilfield. Early stage of development, the formation pressure, the Daqing Oilfield in the mining state of flowing. Until the late 1980s of the last century, the Daqing Oilfield turned to mechanical recovery and the end of the mining era of self-flowing well. The test site of the nine plants in oil production witnessed employees, two well kept out spray "black gold".
Daqing Oilfield has developed over half a century, especially in the thin oil layer peripheral oilfields, why again from the spray? Test of the responsible person, the better the large 415 foreign expansion block reservoir conditions, either landscape or portrait, rich and connected reservoir. Straight wells flowing, simply hit the horizontal wells flowing, there must be a technology that can be both vertical and horizontal direction, both directions of the reservoir oil, was possible as at present from the spray phenomenon.
Horizontal well controlled wear layer fracturing is such an aspect to take into account the technology. Horizontal wells across the reservoir and improve the technology of production per well. Its advantage is that a hand horizontal large reservoir, but only hand to seize the horizontal, but attend to the longitudinal, vertical reservoir losing out. Controlled wear layer fracturing of horizontal wells is equivalent to lend the other hand, vertical reservoir of oil to "squeeze" out. Such vertical and horizontal communication, production per well is naturally have been rising.
Aspect to take into account the benefits In addition to spray the perfect embodiment through self through the data show. The test program shows that, if the development of vertical wells produce from the spray phenomenon 165-94 - level 116 wells, well production is only 1.8 tons; If using a conventional horizontal wells, well production could reach 7 tons; horizontal wells The development and application of large-scale wear layer fracturing process, the stability of the program to calculate a single well can reach the final production of 9 tons, and can be fully utilized geological reserves, will not cause stock losses.
Horizontal well controllable wear layer fracturing test is successful, further promotion for the peripheral field of horizontal well technology to do a favorable bedding. It is understood that the China National Petroleum AG has been to open up large-scale demonstration zone of horizontal wells in the oil extraction plant Gu South area. Demonstration area is a total of 103 wells, 22 wells in the use of such fracturing, has entered the scene stage.
