With coupler embedded and acceleration sensitivity compensation design, the structure symmetry is insured, which can induce the acceleration sensitivity effectively. The acceleration sensitivity compensation design also improves the production efficiency of FOH for towed linear array application.2. A good theoretical simulation platform, utilizing the method of elastic mechanics and the finite element method, is established, which can provide an effect predictive design for FOH. The experimental results are in good agreement with the theoretical analysises.3. Some key technology problems in the making of FOH for towed linear array application are conquered. The new developed FOH, with an acoustic sensitivity of -143.0dB, has acceleration sensitivity less than -30dB, which exceeded to results from other international reports.

At the super-low permeable reservior sandstone of Fu and Yang in Daqing Oilfield, many pore throats exist a lot in the types of compacted and restored flakes and curved lamellas while the pore volume of micropore and the thin, compacted and shrunken throat that contribute little to flow take large scale in the total pore space. Thereof high filtrational resistance is caused by much trouble including high content of reservoir shale, serious sensibility to pressure at waterflooding, remarkable effects of undersaturation and water blocks in micropore. A method with laboratory experiment, theoretical confirmation and field application included was adopted to analyze the non-linear flow characteristics, to reveal the deep mechanism of pinhole enveloping macropore and to provide a new technology of improving the development effect. The outcomes aquired are as follows: Multiple cores with different low and super-low permeability were selected to perform seepage experiments by gas, water and oil. Three fields of flow were observed in the reservoir at different low and super-low core permeability. They are pseudo- elastic flow, transition flow and plastic creep flow. So the concept that there was no correlation of rocky absolute permeability with fluid properties that pasted itself was broken up. Two-phase seepage of water displacing oil in uniform super-low permeability shows that the two-phase seepage zone is narrow.
