"The Borehole seismic multi-wave high resolution image exploration method applied in the fine reservoir description”--a new method to describe and evaluate oil storage. This new method contains Walkaway Vetical Seismic Profiling prospecting technique (W-VSP for short), and Crosswell Seismic Imaging. It is the convergence and extension of the surface seismic methods and geophysical well logging. This method use higher frequency and have higher resolution than surface seismic method , more survey area and depth than geophysical well logging. Therefore, it has been widely regarded as a advanced method to enhance exploration resolution and range, and is researched and promoted by international geophysical exploration domain.
Borehole Seismic Exploration Multi-Wave Image Acquisition System(ordinarily called borehole CT )is a complete set of high-intelligence equipment applied the above-mentioned high-tech services. It uses linear accelerating pulse source to make broadband acousticwave excitation in one oil well, and receive the signal through multiple 3D acquisition system in another well simultaneously. Then the acquired data is processed and finely interpreted and the imaging information is obtained. Through the decomposition and synthesis of the 3D acquisition data and the arithmetic of image reconstruction, we can get high resolution image of crosswell, accordingly to delineate structure , evaluate reservoir parameters, optimize exploration plan , for the purpose of seeking residual oil and enhancing oil recovery.
The innovations of this method are using advanced aerospace propulsion system, linear accelerating technique, and the technique whose intellectual asset we own independently, which contain inventive patent, new practical type patent and six other items of innovation. Under conditions of deep well , high corrosion, strong interference, we have completed controllable excitation apparatus and high-speed acquisition and transmitting system with high-precision, high reliability and militarization, the technology is world advanced level and the domestic first .
The company's after sales services provide oilfield operation with the following:Engineering Design, Field Operation, Data Acquisitio, Processing and Interpretation, equipment sale and service.
The technique burea of CNPC organized the pilot test and the attended experts recognized that the domestic crosswell seismic equipment, the data acquisition, processing and interpretation technique, have the condition to spread on site. Under the support of The technique burea of CNPC exploration and development Institute, with improved auxiliary equipment, our company now is devoted to field technique service in order to promote the upgrading and structure optimization of the traditional industry.
The company is committed to start with the international advanced seismic imaging techniques , research and developer the technical services products in oil and natural gas industry with high-resolution and low_cost, provide efficient, accurate and comprehensive technical service. The company is strategically allied with oil companies home and abroad, become their mutual beneficial partner.
The company goals are:
"To expand science technology and culture,
To spread modern civilization far and wide."
