China Petrochemical News Network News Since this year, the Third Oil Production Plant of the Northwest Oilfield has closely focused on the goal of 10 million-ton oil and gas field construction, actively implemented the development strategy of "carbon fragmentation and oil and gas", and continued to deepen the detriment of condensate gas reservoirs.
We will continue to improve the development of natural gas and further create new profit growth points for oilfield production and operation
.
Since it was put into development in 2009, the early stage of the TP12-8 well area has mainly relied on the deployment of new wells to increase productivity, and the overall reserves of the well area have been relatively low
.
In order to speed up the pace of productivity construction, the plant found that TP226XCH has a good oil and gas display in the Cretaceous Shushanhe Formation when treating Ordovician low-yield and low-efficiency wells.
Through careful comparison and analysis of various logging curve parameters, it is believed that the well has The Cretaceous production potential of the up-return filling hole has been increased to 10 million cubic meters
The success of the well test has further strengthened confidence in the potential research of clastic rocks.
Through continuous enhancement of geological understanding, fine reserve characterization, and the use of Ordovician suspended well bore resources in the reserve area for unused reserves, the implementation of upward return The 4 wells were supplemented with holes and layers, and the daily oil production increased by 30 tons/day, and the daily gas production increased by 60,000 cubic meters/day, which improved the production of reserves in the well area and ensured the continued stability of natural gas production in the well area
.
At the same time, in the special activities for long-stop well management, through the Cretaceous logging display of all the lay-up wells in the jurisdiction one by one, through the comparison of small layers and the analysis of oil and gas accumulation rules, the search is outside the mature well area.
With high-quality reserves, we will continue to advance the rolling edge expansion of gas reservoirs
.
Through the implementation of geo-engineering integration and underground and ground integration, the evaluation of refilling holes and layers in the outer expansion area will be accelerated
.
Well TP13 is a Paleogene parked well located in the northern part of the TP12-8 well area.
In the process of demonstration of the potential of the Cretaceous refilling and reforming layers, the technicians comprehensively considered geological risks and potentials, engineering difficulties and benefits, and underground-surface related supporting facilities.
