The Great Wall drilling logging interpretation of "water pumping oil" initial success
China Petroleum network news, as of July 23rd, the oil test report shows that there are 44 exploration wells, according to the proposal to obtain industrial oil flow. The Great Wall drilling and logging company explained and evaluated the results of "pumping oil in water" in Northern Shaanxi province.
In recent years, Changqing Oilfield Exploration and development has entered a new stage. The Great Wall drilling logging company in the interpretation and evaluation of service adjustment, the transition from exploration to development, and the interpretation and evaluation of Liaohe oilfield application of mature "water flooded layer interpretation and evaluation application" and "the old wells tapping the remaining oil and other cases in a timely manner to promote the party.
The Zhidan Ansai area of Changqing Oilfield is affected by geological structure and lithology. The difficulty of logging interpretation and evaluation is how to select the dominant reservoir which can produce industrial oil flow from most of the water out blocks. The technician is called "fishing for water" in an image".
In order to do "pumping oil in water", the Great Wall drilling logging company has paid more attention to reservoir oil information and gradually extended to the microscopic field of reservoir management. Especially through the excavation and application of conventional physical properties data and T2 spectra, the reservoir properties and oil-bearing properties are organically combined, and the promising reservoirs are summarized, which guides the interpretation and evaluation of exploratory wells. This method has achieved good results in comprehensive interpretation of oil exploration well and gas well. After the oil production of Xin 188 well, Ba 1 well and Mu 133 well in this oil field, high yield industrial oil flow has been obtained.
At the beginning of this year, the Great Wall drilling logging company of Zhidan - Ansai area will be long 9- 10 oil and water as the key poverty issues, the formation of Dingbian research team, summed up the block is a physical property, lithology, electrical properties and oil-bearing characteristics of cluster analysis on oil content, water features, summed up a set of logging characteristics the technology of effective interpretation methods, to improve the "water pumping" success rate, accurate evaluation of oil and gas and water qualitative reservoir, provides the geological basis and data support for the effective exploration and development for Party B.
